Meat and Milk Institution is implementing red meat sales through grocery chains in order to ensure stability in red meat prices in Turkey. In this study in order to evaluate the effectiveness of this policy from the perspective of consumers, data set obtained from 388 households in Gaziantep city center was used. According to the findings, it has been determined that 53.6% of consumers prefer contracted markets due to the suitability of red meat prices. Initially, all consumers bought red meat from contracted markets, but it was found that 62.11% of them gave up buying red meat from these markets. This situation was found to be quite remarkable and logit model was used to determine the factors affecting the continuity of red meat purchase of households from contracted markets. According to the Logit model results, it was observed that households buying red meat from the contracted markets were affected by the variables that they are care about the price of red meat, income and frequency of shopping at these markets. As a result, it can be stated that this policy implemented by the ESK is aimed at selling red meat to low-income consumers rather than providing price stability and does not have a demand increasing effect.

Bu çalışma; Şanlıurfa ve Gaziantep sınırları içinde bulunan Karkamış Baraj Gölü’nün fiziko-kimyasal özelliklerini ortaya çıkarmak amacıyla Ocak-Aralık 2015 tarihleri arasında belirlenen 5 istasyonda yüzey ve 4 ve 8 m derinliklerden su örnekleri alınarak gerçekleştirilmiştir. Alınan su örneklerinde yıl boyunca sıcaklık, pH, çözünmüş oksijen, elektriksel iletkenlik, amonyum azotu, nitrat azotu, orto fosfat fosforu, toplam azot ve toplam fosfor ölçülmüş olup tespit edilen değerler sırasıyla; sıcaklık (14,3-21,6°C ortalama: 9,4), pH (8,4-9,1-7,8), çözünmüş oksijen (9-10-11,8 mg L-1), elektriksel iletkenlik (251-332-412 µS cm-1) amonyum azotu (0,003-0,069-0,194 mg L-1), nitrat azotu (1,549-2,292-3,473 mg N L-1), nitrit azotu (0,001-0,006-0,053 mg L-1), orto fosfat fosforu (0,007-0,034-0,076 mg L-1), toplam azot (0,722-1,154-1,696 mg L-1), toplam fosfor (0,007-0,016-0,026 mg L-1) bulunmuştur. Karkamış Baraj Gölü’nde fizikokimyasal parametrelerin aylık olarak farklı derinliklerde değişimini izleyerek, su kalitesi özelliklerine ve sucul yaşam açısından uygunluk seviyesi ile Yüzeysel Su Kalitesi Yönetim Yönetmenliğine göre I. Sınıf yüksek kaliteli su sınıfında olduğunu göstermektedir.

Fruit flies (Diptera: Tephritidae) is one of the most important Diptera families, some species damage fruits, and cause millions of dollars in every years. In this study, adult fruit fly materials were collected from Gaziantep province between 2010 and 2021 from possible host plants using insect net. Obtained materials were examined, and were determined that 15 species. All species recorded for the first time from Gaziantep province. In addition, Goniurellia tridens (Hendel, 1910) recorded as a new record from Turkey. With these contributions, Gaziantep fruit fly fauna increased to 44 species. In the article, examined materials, current list of Gaziantep fruit fly fauna and adult and wing figures of Goniurellia tridens (Hendel, 1910) were given.
